So Importing the Transport Requests is the critical. Sometimes by mistake if one click on the button Import All in the production environment all the Transport Request which is in released status or already Imported to Production can be directly Imported to the production environment (Which may not be required in the Production). This will create great impact in the production Server.To avoid such situation, IMPORT ALL Icon should be disabled in STMS.Procedure to Disable IMPROT_ALL Icon in STMS:-1) Go to STMS Tcode

2) Go to Menu Option Overview

3) Select System4) Choose SAP SYSTEM

5) Go to Transport Tool Tab

6) Create Parameter "NO_IMPORT_ALL" with value 1 (True)

7) Save it.
